Final answer:
The need to buy and install Middleware for different computers in a LAN due to lack of standardization is false, as LANs use standardized networking protocols like TCP/IP for communication.
Step-by-step explanation:
The statement that we have to buy and install Middleware to overcome lack of standardization in different computers in a Local Area Network (LAN) is False.
Middleware is software that allows different systems to communicate with each other, making it easier to work with a diverse set of technologies.
However, the main purpose of a LAN is to connect computers within a limited area so they can share resources like files and printers without the need for middleware.
This is typically accomplished through already standardized networking protocols such as TCP/IP that ensure communication regardless of the underlying hardware or operating systems.
